This exhibit, an R2 rectifier, by Micromesh dates from 1934. The unusual feature is the V orientation of the anodes.
Both anodes have small cylindrical cavities containing the cathode and considerable extra wing area for cooling.
The balloon envelope is 77 mm in diameter, and excluding the B4 base pins is 100 mm tall.
